I am getting following error when trying to upgrade python version please advise.
The issue may be related to the network firewall/proxy or ZScaler.
Please try the following workaround to set the trusted host to Python as follows:
pip config set "global.trusted-host" "pypi.org files.pythonhosted.org"
Then run your Python upgrade command(s).
If the problem still persist, I highly recommend you contact the ZScaler support team.
